RestTemplate乱码和No HttpMessageConverter for java.util.HashMap and content type “application/json

乱码问题如下所示
解决方案，设置转换器

private StringHttpMessageConverter m = new StringHttpMessageConverter(Charset.forName("UTF-8"));
private RestTemplate restTemplate = new RestTemplateBuilder().additionalMessageConverters(m).build();

如果要传递json数据可能遇到No HttpMessageConverter for java.util.HashMap and content type "application/json
需要再改下RestTemplate对象。

    private StringHttpMessageConverter m = new StringHttpMessageConverter(Charset.forName("UTF-8"));
    private RestTemplate restTemplate = new RestTemplateBuilder().additionalMessageConverters(m).additionalMessageConverters(new MappingJackson2HttpMessageConverter()).build();

修改后成功，如下图所示
